Abstract: The Regional Model of the Ocean Refined Adaptively (REMORA) is a new implementation of an existing community standard ocean model, the Regional Ocean Modeling System (ROMS, Haidvogel et al., 2008;Shchepetkin & McWilliams, 2005) that simulates estuarine and oceanic dynamics using the latest high-performance computing architectures.REMORA employs hierarchical parallelism using an MPI+X model, where X may be OpenMP on multicore CPU-only systems, or CUDA, HIP, or SYCL on GPU-accelerated systems.It is able to be built and run in both single and double precision.REMORA is built on AMReX (Zhang et al., 2019(Zhang et al., , 2021)), a block-structured adaptive mesh refinement (AMR) software framework that provides the underlying performance-portable software infrastructure for block-structured mesh operations.REMORA, like ROMS, is a regional model, meaning that it is generally used for limited domains, and as such requires boundary conditions derived analytically, or from larger-scale models.
